英文摘要：

[Bmim] Cl-AlCl3 ionic liquid was used as catalyst in the Ffiedel-Crafts acylation of anthracene with oxalyl chloride to synthesize the important macromolecular intermediate 1,2-acean- thrylenedione. The results showed that the suitable synthesis conditions of the acylation reaction were as follows ： the molar ratio of AlCl3 in [Emim]Cl-AlCl3 ionic Uquid was 0.67 ,the mass ratio of [ Emim] Cl-AlCl3 versus anthracene was 2, the mass ratio of oxalyl chloride versus anthracene was 2, the reaction temperature was 40 ℃, and the reaction time was 6 h. Under these conditions, the yield of 1,2-aceanthrylenedione was 91.5% with the selectivity reaching 98.3 % . Furthermore, [ Emim] Cl-AlCl3 showed less pollution to the environment and could be recycled. Under the same reaction conditions, the effects of AlCl3, FeCl3, [ Emim] Cl-AlCl3 and [Emim]Cl-FeCl3 at the same tool quantity on the yield and selectivity of 1,2-aeanthrylenedione were studied and the results indicated that [Emim] Cl-AlCl3 was the most effective catalyst. Pure 1,2-aceanthrylenedione was prepared by extraction and recrystallization and the structure of 1,2-aceanthrylenedione was identified by melting point measurement, GC/MS, Fr-IR and 1HNMR analyses.
